my gap gauge only goes to 85 thousandths and most of the plugs were well past that. surprisingly, still ran fairly decent

Thanks to one coil for every plug nowadays. It boggles my mind how long they last now but they actually start wearing out from day one.my gap gauge only goes to 85 thousandths and most of the plugs were well past that. surprisingly, still ran fairly decent
If it was on the '08 that's mentioned in his sig and he didn't encounter any problems then I'd say it's likely that he did the appropriate preparation before attempting the removal.I realize we're the non-stuck generation of 5.4s (purportedly), but was there any challenge removing them (other than the ladder!)?
I would change ALL of them at 50k miles or less. I change mine every 30k miles. they slowly erode your MPG's and HP from day one. I find them easy to change and the stealers charge way too much. Your 2011 has the new style plugs anyway.With other cars I've learned to wait until misfire (plug or coil) then at that time do all plugs, and if on a rear bank of a transverse - do all coils in the back as well. Any reason I should change with my '011? It sounds like access is not bad and there is limited benefit to changing them early. Thoughts?
Sorry about the oil analysis posts, I wish I never wrote those even though I doubt if they are worth getting 90% of the time. As for the plugs; that whole operation costs me $45 and about 1 1/2 hours time max but I keep forgetting not everyone was a mechanic..............sorry.And you berated me for doing engine oil analysis to extend intervals, save money - saying it was a waste of money - all hogwash. Now you're talking about blowing hundreds of dollars at least twice as often as needed? You're a funny man - talk about wasting money!
